11 Claims.

This invention relates to an improved sewing machine unit, and in one of its more specific aspects, to such a unit wherein a sewing machine and a power transmitting means, including an electric motor, are supported in spaced relation on an upright standard.

One of the objects of this invention is to provide a sewing machine unit, including a sewing machine and power transmitting means, including an individual motor, on a portable support in a compact and convenient arrangement, and in such a manner that the operator is permitted maximum freedom of his hands and arms in manipulating and sewing various articles.

Another object of the invention is to provide a sewing machine unit of the character indicated wherein the sewing machine and the driving unit are disposed on opposite sides of an upright standard, in spaced balanced relation, and so arranged that the sewing machine is disposed substantially wholly intermediate the standard and the position normally assumed by an operator of the machine, while the motor forming the power source for the driving unit is disposed on the opposite side of the standard. As a result, the operator is subjected to a minimum of objectional heat developed by the motor in the course of its normal operation. Moreover, this arrangement is such that the standard is in advance of the arc of movement of the hands of the operator in manipulating the work, thus insuring maximum freedom of action.

Another object of this invention is to provide a sewing machine unit of the type indicated that is capable of utilizing known types of sewing machines for stitching tubular articles, such as overalls and the like.

Another object of the invention has been to provide a sewing machine unit, including a sewing machine proper and various operating devices isposed on opposite sides and in spaced relation to an upright support which is so constructed as to eifectively reduce noises incident to the operation of the unit as a whole.

Another object of this invention is to provide a sewing machine unit of the character indicated having direct operating connections from suitable foot-actuated control treadles to various devices, such as a power transmitting unit, a presser bar, and an oil pump.

A further object of the invention is to provide a sewing machine unit, including a substantially vertical standard, a sewing machine and power transmitting means disposed on opposite sides of the standard and in spaced relation thereto, foot control means for actuating various devices of the unit, and work supporting platforms, all arranged in suitable predetermined relation to obtain a balanced structure that may be readily and advantageously employed in carrying out various stitching operations.

A still further object of the invention is to provide a sewing machine unit of the character indicated that is relatively simple and rugged in construction and that may be readily moved from place to place.

The sewing machine unit of this invention involves, in its basic aspects, a base having a substantially vertical, hollow tubular standard extending upwardly therefrom. A support is secured to the upper end of the standard and carries a sewing machine unit of desired type to one side of the standard and a housing to the other side of the standard. Within the housing is a power transmitting unit, including a motor having a driving shaft for imparting rotation to a parallel main shaft of the sewing machine through the medium of a short belt connection. The sewing machine is disposed between the standard and the position normally assumed by the operator during operation, but in such relation as to provide maximum freedom for the manipulation of the work within a minimum overall space requirement, while the motor of the power transmitting unit is disposed remotely from such position of the operator. Also within the housing is a blower communicating with a conduit extending through a wall of the housing and over the top of the sewing machine, this conduit having a gooseneck portion for directing a stream of air under pressure in a manner to cool the needles of the machine and keep the work support clean. Various control devices are contained within the housing, including a lever for actuating the presser bar and a lever for controlling the operation of the power transmitting unit to place the same in and out of service as desired. Additionally, a pump arrangement is provided for transmitting lubricating oil to various devices within the sewing machine. Suitable foot treadle connections provide ready control of the presser bar, the lubricating oil pump, and the power transmitting mechanism, as will be hereinafter more fully described.

Noises incident to the operation o the unit are successfully minimized by providing suitable insulation within the hollow tubular standard. Such insulation may be in the form of a coating of a sound absorbing material on the inner surface of the hollow standard, or may be in the nature of a 3 mass of sound absorbing material substantially lling the entire length of the standard.

In the seaming of certain garments, it is often necessary that a left-hand member be joined to a right-hand member. To facilitate such an operation by the practice of this invention, I provide a swingable platform supported above the base for carrying a supply of left-hand members and a platform carried by the standard `for holding a supply of right-hand members. This results in a convenient arrangement whereby the operator may readily pick up a member from each of the platforms and sew them on the sewing machine of the unit without necessitating Vstooping over or reaching into a basket or .other source of `supplyeither to one side of or behind the operator.

With the above and other objects in View, the invention comprises the devices, combinations and arrangements of parts set forth in the ,fol-

lowing detailed description and illustrated in the annexed drawings of preferred embodiments of the invention, from which .the several features of the invention, together with the advantages attainable thereby, will be readily understood by persons skilled in the art.

Figure 12 is a side elevation View of still another embodiment of the sewing machine unit of this invention.

Referring now to the drawings wherein like reference characters denote corresponding parts throughout the several views, and more particularly to Figures 1, 4 and 5 thereof, the base of the sewing machine unit is generally indicated by numeral l and is formed with a pair of openings H and l2 to accommodate foot treadles I3 and Hl, respectively. Treadle I3 is affixed to a rock shaft l5 that is suitably journalled at .opposite ends in a pair of bearing sleeves or the like i6 and ll, while treadle lil is mounted for tilting movement about the axis of a stub shaft SS that has its opposite .ends disposed in bea-ring sleeves or the like I9 and 20 in the base lll. An upstanding split sleeve 2l is preferably formed integral with the base and is adapted to receive and securely clamp, by means of a series of screws 22, the lower portion of a substantially vertical hollow tubular standard or post 23.

A bracket support 25 is provided with a depending split sleeve 2S that embraces the upper end portion of post 23, a bracket member 2l exn tending to one side of post 23, and a housing 23, that is preferably rectangular and open at the bottom, extending to the other side yof post 23. A collar 29 is vertically adjustable along post 23 for varying the vertical position of bracket support 25 and the devices carried thereby. Split sleeve 2S may be maintained in any desired anu guiar and vertical position with respect to post .23 4by means of screws 32.

A ysewing machine 3l is carried by bracket support 25 tothe lef't side and forwardly of post 23, as viewed in Figures 1 and 2. This is accom- 'plishe'd by rigidly attaching the outer` end of bracket member 21 to the upper frame 32 of the sewing machine. The sewing machine may be of any desired construction but, as illustrated in the drawings, is preferably of the type disclosed in Christensen et al. Patent No. 1,741,095, granted DecemberZll, 1929. The portion of the frame disclosed in that patent, which extends into a base or standard by which the machine is lsupported from a table or the like, is simply eliminated in the instant arrangement, as will be readily observed .from an 'inspection Kof Figures 1 and 2, thereby providing 'for greater freedom Aof lateral movement of the operators hands and arms in the course of the operation of the machine. 1t will 'be noted further that the sewing machine is spaced from both 'base 1U and post 23, resulting in adequate clearance and ready access to the various stitch-forming and control devices which will 'be identified hereinafter.

'The details of the interior mechanism of sewing machine 3l form no part of the present in vention, and hence it is not deemed necessary that this construction be described. It is considered sufficient, for the purposes of this de scription, to identify a number of the essential elements and .devices of the sewing machine shown in the drawings. The upper frame 32 of the machine has a needle head 33 suitably attached thereto and extending laterally .of its forward end. The needle head has a needle bar Sii and a presser .bar .35, `both of which are mounted for vertical movement inthe usual manner. Depending 'from the rearward end of upper frame 32 is a hollow member '36 to which is attached a work supporting arm or member 3l extending forwardly below, ybut at an acute angle to, the upper frame member. ,As is 'best shown in Figures 1 and `2, the free end of the work supporting arm is located beneath the needle head. It is` provided with necessary Work feeding devices, loopers vor other stitch-forming'means (not shown), adapt ed to cooperate with theneedles carried by needle bar. Reference may 'behad tothe above menn tioned Christensen et al. patent vfor further details as to the construction and operation of the stitch-forming and work-feeding devices and the operating means therefor. v

Disposed within and projecting beyond Athe forward end of upperrame 32 is .a rotary main `shaft 38, Whose axis is indicated by line A-A (Figure 2) for actuating needle bar 134 .and the stitchforming and work-feeding devices of the sewing machine. This shaft has a combined handwheel and pulley 33 secured .to its projecting end. It is recommended .that the Vhandwheel be substantially larger in diameter than those customarily employed with similar sewing machines. `By .pro-

viding such a larger handwheel and by having the machine frame constructed and arranged as illustrated, the lower portion of the handwheel may be readily grasped and manually actuated by the operator by a forward movement of the right hand without necessitating the withdrawal of the entire arm from its general operating position, as is necessary in the case of :the machine frame disclosed in the earlier mentioned Christensen et al. patent. This will be readily apparent 4from an inspection of Figure 1. The combined handwheel and pulley is connected by a relatively short open belt with a drive pulley 4i secured to the forward end of a driving shaft 42 of a power transmitting mechanism 43 that includes a motor 43a, and that is contained within housing 23. The power transmitting unit may, for example, be of the type disclosed in the patent to Peets et al. No. 2,004,055, granted June 4, 1935. The axis of driving shaft 42 is denoted by line B-B (Figure 2), the same being parallel to axis A-A of main shaft 33 of the sewing machine. With the construction just described, and as is illustrated in Figures 1 and 2, the sewing machine 3l is arranged wholly forwardly of tubular post 23, while motor 43a of the power transmitting unit is positioned rearwardly of tubular post 23 and remotely from the position normally assumed by the operator of the unit, with the result that the operator is subjected to a minimum amount of objectionable frictional heat developed by motor 43a in the course of operation.

A cover plate 44 is detachably mounted on the forward end of the housing by a series of screws 45 to permit of ready access to drive pulley 4I when it is desired to attend to replacements, repairs or adjustments thereof. The power transmitting mechanism is contained and suspended within housing 28 through the cooperation of a bracket 45 and a series of screws 41 that project through slots 48 in the top wall of the housing. interposed between the under surface of the top of the housing and bracket 4B are a plurality of vibration insulators 49 composed of a suitable material, such as natural or synthetic rubber or the like. Bracket 43 includes a depending arm '53 that is tapped to receive an adjusting screw 5l which is operated from the exterior of the housing by a screw driver or other suitable tool, and which is constrained against axial movement by a collar 52. Through the coaction of bracket 45, suspending screws 41 and adjusting screw 5l, the position of power transmitting mechanism 43 within housing 23 may be readily varied, as required, to obtain proper tensioning of belt 40. Lateral shifting of the bracket 46 in the manner indicated is permitted by the elongated slots 48.

Also disposed within housing 28 and actuated by power transmitting mechanism 43 is a blower assembly 53 having a discharge outlet 54 (Figure l). A tube 55 having an end portion bent in the shape oi a gooseneck 53 extends through a boss formed in a side wall of housing 28 and is clamped thereto by means of `a split sleeve '51 which is tightened by a set screw 58 accessible from the exterior of the housing. Communication between the end of tube 55 within housing 28 and blower outlet 54 is established by a ilexible tubular connector 59 formed of rubber or a suitable plastic or the like. In operation, a continuous stream of air under pressure discharged from blower assembly 53 through outlet 54, flows through ilexible connector 59, through tube 55, and is then directed by gooseneck 56 to the region of the needles carried by needle bar 34 for the dual purpose of cooling the same and blowing away lint and other foreign particles that may be present. The construction and arrangement with respect to this phase of the invention may vadvantageously be similar to that disclosed in the application oi Charles F. Rubel Ser. No. 433,740, led March 7, 1942, now Patent No. 2,423,996, July 15, 1947.

Power may be supplied to the motor of the power transmitting unit by an electric cable 60 which extends downwardly from an overhead line (not shown) through the hollow interior of a vertical conduit Si that is threadedly coupled at its lower end to Ithe top wall of housing 28. Conduit GI also serves as a support for a pair of C-shaped frame members 52 that are positioned at right angles to each other, and that may be of the type disclosed in pending application of Clarence C. Smith Ser. No. 513,504, led December 9, 1943, now Patent No. 2,430,332, November 11, 1947. Each C-shaped frame carries a pair of vertical spindles 53 that extend through and support spools 94 of thread 35. Individual strands of thread are passed through corresponding guide openings 55 in the upper portion of the frame members, to thread tensioning devices El, and thence to the sewing machine needles and loopers.

Attached to a rearward corner of treadle I4 and extending upwardly therefrom is a chain or other type oi ileXible connector 10 which is connected Ato a pair of branch chains 'il and 12. Branch chain il is secured at its upper end to a presser bar actuating lever i3 (Figures 1 and 2), which cooperates with a link 14, a lever '15, and devices (not shown) within needle head 33, to move the presser bar 35 upwardly, when treadle I4 is depressed, against the action of a spring member 'it that normally urges and maintains the presser bar in downward position. The mechanism for this purpose within the needle head may be similar to that shown in Christensen et al. Patent No.V

1,773,028, granted August i2, 1930. Upon release oi pressure on foot treadle I4, the parts return to the relative positions illustrated in Figure 1, due primarily to the action or spring member 73.

The actuation of foot treadle E4 also operates a pumping system for lubricating various parts within the sewing machine by a mechanism that will now be described, having particular reference to Figures l, 2 and 3. In this connection, there are provided a bell crank Ti, which is pivoted at 'd8 and has one arm connected with the branch chain 72, and a double-acting pump 'i9 that may be of the type disclosed in Clarence C. Smith application Ser. No. 541,902, iled June 24, 1944, now Patent No. 2,430,370, November 4, 1947. A link 39 may connect the other end of bell crank `'il to a reciprocatory piston 8l oi a pump cooperating with aplurality of conduits, such as those indicated at 82 and S3, for transmitting lubricating oil to the sewing machine parts. For further details as to the construction and opera tion oi the double-acting pump, reference may be had to the above mentioned application of Clarence C. Smith. It suilices to point out that when foot treadle i4 is depressed, chain l0 and branch chain 12 are moved downwardly,v urging bell crank 1l in a clockwise direction about pivot 'i8 (as viewed in Figure 3) thereby moving piston 9! toward the left and forcing lubricating oil through one of the conduits 32 and 33 to certain of the sewing machine devices, whereas upon release of the treadle the piston is moved in the opposite direction to lubricate other parts.

afrsse i Itis hence. observed that upon depressing foot treadle I4, presser bar 35 is moved upwardly and simultaneously therewith lubricating oil is transmitted. to various devices within the sewing machine.

Referring next to Figures 4 and 5, a sleeve 85- is mounted. on rock shaft l5 by screws 8G and carries a rock arm 81 which is coupled toa pitmanV rod 88 at its free end. The pitman rod extends generally upwardly and issecured` at its upper end toa lever 8S. (Figure 2) for operating the usual clutch (not shown) of the power transmitting mechanism whereby the latter may be readily placed inr andV out of service, as desired, by simply depressing foot treadle i3. Ii desired, branch chainl 'l2 may be disconnected. from the upper end of chain it and connected to pitman rod 88 tothereby actuate the double-acting pump mechanism in response to operating foot treadle I3.

As was indicated earlier herein, the seaming of. certain` garments, such as overalls and the like,.by the sewing. machinedepicted in the drawings, requiresthe joining together of a left-hand member to a right-hand member. tion. is` facilitatedin accordance with the invention, by equipping the unit with a pair of suitable platforms or trays as will now be described. Secured to the rearward left-hand corner of base Hl- (Figures l and 4) and projecting substantially vertically therefrom, is a tubular post 90. A bracket arm 9i, having a hollow sleeve-like portion: s2 at one end, receives the upper end of post 90 andv is. adjustably secured thereto in desired4 vertical or angular relation by means, of set screws 93. A platform or tray 9tis aiiixed tobracket arm, Si by screws 85 that are preferably counter-sunk to eliminate obstructions onthe upper surface-of' the platform. A stack of lefthand` members of the garment may be placed on platform Sii which is swingable to any desired angular position with respect to the base of the sewingy machine unit. A second platform or. tray Sily issimilarly attached by screws S8 to a bracket arm. 99: having one end portion so formed as to embrace.V post 23 and be-clamped thereto by one or more screws 108. It will bev apparent that platformV 97 is vertically and angularly adjustable with respect topost 23. A stack of righthand garment members may be placed on platform Sl.

One of the features of this invention resides in the provision of means for reducingand dampening noises incident to the operation of the power transmitting mechanism 413, the sewing machine 3l; and other devices of the-unit. I have foundy that objectionable noises may be materially reduced by placingv a coating or liner ot sound absorbing material till, such as natural or synthetic rubber, along the inner surface of tubular post 23, or by placing a closure: |92 across the lower end of post 23 and substantially llingv the interior of the post with a mass of solid sound absorbing material, such as sawdust or the like. Ii' desired, post 23- may be provided with a; liner l-I and then filled with sound absorbing material 103;

One. modification of the sewing machine unit isillustrated inFigures 8 and 9, and contemplates locating the chains or other flexible control devices within hollow tubular standard 23, as dis'- tinguished1 from placing the same exterior of the post 23, as shown in Figures 1, 2 and 4. Referring to Figure 8, treadle I4 is amazed by one or more set: screws |05 to its support shaft 106, which This opera- 8 extendsinto base t0 of the sewing machine unit. Asleeve lill is attached to shaft H36 by set screwsV IUS and carries an armv 09 which projects` into the region directly below post 23. A chain Htl-isv securedy to the free end of lever H19' and. to an. end of a presser foot lifting lever i l iv that. cooperates with link ifi, lever l5 and devices. (not shown) within needle head 33 for movingV the presser bar upwardly against the action ot spring. member 'i6 when treadle I4 is depressed inthe same manner set forth inY connection with therst describedembodiment of the invention,

rIlhe lubricating. pump is also actuated each time foot treadle lil is depressed through aV connectionprovided byA a second chain H2 connectedf at its lower end to the free end oi arm H18 or# tol a point on the chain HU and at its other end toay bell crank H3 which is in turn coupled to pump piston 8| by a linkage Sil'. It will be'observed that chains Hi! and H2 both entend` upwardly through the interior of hollow 1105i.

A sleeve M5 ismountedv on rock shaft l5 by screws M-S- and carries a rock arm lll which is coupled at itsiree endto the lower end of pitmanA rod.: 88x The-pit-man rod extends upwardly within. the connes of postv 23 and is secured at its upper end` to lever 139v for operating the usual clutch: (not shown) of the power transmitting mechanism! whereby the power transmitting mechanism. may readily be placed in and out of service asl desired, by simply depressing foot treadle i3.

In` the embodiment of the inventionv shown in Figuresy l0 and 11, housing 28, within which the power transmitting. devices are contained, is disposed directly above and is mounted. on the upper endof hollow post 2-33 andthe sewing machine unit isconnected thereto and extends laterally therefrom: as illustrated. In this embodiment of the invention, thel rotary main shaft 38 of the sewing machine unit is directly in line with the shaft'oithe-motor 43o, of the power transmitting mechanism andA is driven by said motor through ay clutch without-the use of a belt.

In. instances where it is desirable to have a belt drivebetweenthe motor and the main drive shaft of the sewing' machine unit,l the arrangement shown.4 in- Figure l2 may be employed. In this modifica-tion of the invention the motor and clutch unit ismounted at4 the upper end of the standard, as: in: Figure 11, while the sewing machine unit. issuspended below and to one side of housing 2-8 by a: bracket or frame member H29. Rotation ofthe shaftof motor 43a is transmitted tomain shaft 38` of the-sewing machine through drive pulley- 4l, belt 121i, and combined handwheel and` pulley 39. It will be noted that this particular arrangement permits of ready access to combined handwheel. and pulley 39, full freedom of movement.- ofthe operators hands, and excellent visibility in performing the stitching operations.

It-Will be understood. that ineither of the arrangementsishown in Figures 10, 11 and 12 the control. means of either Figures 1 to 5, or 8 and 9 may be employed.

Itis believedthat the objects, advantages, construction and operationof my present invention willlbereadily4 understoody from the foregoing by persons-skilled. in the art. By reference to-the drawings, outstanding advantages of the particular constructions and arrangements disclosed are thefreedomV ofmovement provided for the operator inthe manipulation of the work andthe comfort W-thr which' the' operator may use themachine. The nrst advantage is achieved by the particular relationship provided by the relative positions of the sewing machine, the electric transmitter unit, and the supporting pedestal. Work supporting arm 37 of the sewing machine is so disposed that the operator may swing his hands freely in arcs extending from the stitching point outwardly as far as desired, without interference with the pedestal or standard 23 or any other part. The second advantage is achieved by making the stitching point visible to the operator without the necessity of leaning to one side and also by locating the transmitter, with its driving motor, at some distance from the operator. Itis to be borne in mind, however, that various changes in the forms of the invention herein illustrated and described may be resorted to without departing from the spirit of the invention or the scope of the appended claims.
